“…These authors observed that interventions might be more effective for children of parents with lower education (Feinberg & Kam, 2008). Sandler et al (2018Sandler et al ( , 2020, Cookston et al (2007), andPelleboer-Gunnink et al (2015) observed that children's age, time since divorce, or gender might influence the intervention effects. Nevertheless, whereas some results clearly present the direction of the influence of these variables, such as, for example, those who are more recently divorced benefit more (Pelleboer-Gunnink et al, 2015;Stathakos & Roehrle, 2003), the information regarding the differences in the intervention efficacy between sociodemographic groups is still scarce and contradictory, so more research is needed in this regard (Sandler et al, 2020).…”
